I just built a micro tri copter based on Davids version on RC Explorer.
I used a standard frame but 6" arms and 10 gram Hextronik motors from Hobby King, 6X3 3 blade props, Turnigy 6A ESC's and a KK Ver 5.5E board with KR 2.5 Tricopter Firmware.
I used a servo tester to center my servo before mating it direct drive as David did to the tail motor assembly.
When I power up when viewed from the back the servo travels completely to it's left most limit.
There is no servo control until the board is armed AND the throttle is off of the zero point just before the motors spin up.
At this point I can then use my transmitter to trim the servo to the middle centered / level position but my yaw/rudder trim is all the way to a limit on my transmitter.
Is this normal or do I have something reversed? I have done stick centering and ESC / Throttle calibration.
